Walden was joined in his Medford office by Rep. Dennis Richardson, R-Central Point, who has been pressuring state officials for answers about the lack of oversight of Cover Oregon, which is this state's version of the Affordable Care Act.

Almost 5,000 signatures have been collected on a petition by Richardson calling on the federal Government Accountability Office to audit Cover Oregon.

"We have spent hundreds of millions of dollars and we have nothing to show for it," Richardson said.

The GAO has not yet indicated that it will actually conduct the audit, but Walden said he is confident there will be one based on the number of his colleagues in Congress demanding an audit.
